Graphene coated hollow glass microspheres may be easily prepared by mixing Pristine Reactive Graphene Particles with hollow glass microspheres under conditions to associate the Pristine Reactive Graphene Particles on the external surface of the hollow glass microspheres by chemical coupling with a silane coupling agent to form graphene coated hollow glass microspheres. Graphene coated hollow glass microspheres prepared by the methods as described herein are also provided. In an embodiment, graphene coated hollow glass microspheres comprise a graphene coating formed from Pristine Reactive Graphene Particles associated on the external surface of the hollow glass microspheres by chemical coupling with a silane coupling agent.

A process and a plant produce hollow microspheres made of glass. According to the process an aqueous suspension is prepared from starting materials containing glass powder and water glass, feedstock particles having a diameter between 5 ?m and 300 ?m, in particular between 5 ?m and 100 ?m, being produced from the suspension. The feedstock particles are mixed with a pulverulent release agent made of aluminum hydroxide in an intensive mixer. The mixture of feedstock particles and release agent is subsequently introduced into a firing chamber of a furnace. The feedstock particles expand in the firing chamber, at a firing temperature which exceeds the softening temperature of the glass powder, to form the hollow microspheres.

Compositions and methods for glass composites suitable for tissue augmentation, biomedical, and cosmetic applications are provided.

A fabric includes a first flexible fabric layer, having fabric emissivity properties in a visible radiation range that are selected so as to mimic ambient emissivity properties of a deployment environment of the fabric, and at least one second flexible fabric layer, which is joined to the first flexible fabric layer, and which is configured to scatter long-wave radiation that is incident on the fabric. The first and second flexible fabric layers are perforated by a non-uniform pattern of perforations extending over at least a part of the fabric.

A refractory material for forming a refractory product includes a refractory component and a taggant having an amorphous or a crystalline solid dispersed within the refractory material.
